Grasses exploit geometry for improved guard cell dynamics
Plant Science Research WeeklyStomata are pores on the surface of leaves essential for gas exchange. In grasses, stomatal aperture is controlled by pairs of dumbbell shaped guard cells, with each guard cell surrounded by a subsidiary cell. Despite cell geometry being well described, it was unclear how it influences stomata function.…
Perspective: Multiple mechanism behind plant bending
Plant Science Research WeeklyBending or folding in plants is influenced by different factors such as environmental conditions (nutrient, water, light, gravity), abiotic or biotic stress, cell wall properties, and cell differential growth. Jonsson et al. explain how bending is achieved by considering molecular mechanisms, mathematical…
